MACHINE FOR THE MANUFACTURE OF PAPER PAILS.

SPECIFICATION forming part of Letters Patent No. 244,607, dated July 19,1881. 1 Application filed August 3o, iseo. (No model.)

To all whom it may concern B e it known that I, EBEE HUBBARD, of St.Joseph, Berrien county, Michigan, have invented an Improvement inMachines for Making Paper Pails, of which the followingis aspecification.

`The nature of this invention relates to certain new and usefulimprovements in the construction of machines for the manufacture ofpaper pails, and the invention consists in the peculiar construction ofthe devices employed for forming the croze to receive Vthe bottom, andis particularly designed as an improvement upon the invention for whichLetters Patent of the United States Were granted to me April 20, 1880,and numbered 226,752.

Figure l is a central vertical section. Fig. 2 is atop plan. Fig. 3 is abottom plan. Fig. 4 is a plan view of one ofthe segmental platesdetached.

In the accompanying drawings, which form a part of this specification, Grepresents the press or mold, consisting of a perforated sheetmetal coneprovided' with the top spider, f, which is cent-rally perforated toadmit of the insertion of the rod D, the full construction of thisportion of the invention being contained in the before-mentioned LettersPatent.

In the arms of the spiderf, and in the under face thereof, is formed arecess, a, to receive the annular ring A, which is provided with a stud,b, which projects up between the 4arms of the spidenandby which the ringmay be turned, as desired.

B represents segmental plates7 the inner ends of which are slotted, asshown at n, and through which slots pass screws c into the spider. N earthe outer edges of these plates thereis formed aslot, d, which receivesa downwardly-projecting stud, e, from the spider, and

which serves as guides to the plates as they are advanced or retracted.V A pin or screw, g, projects from the inner face of each segmental vplate into the eccentric slots h in the ring A, the Whole being soarranged that as the ring is turned in one direction the plates B willbe projected a proper distance beyond the face of the cone G, forming anannular ange, which, when the pulp is being pressed to shape, will forma croze in the same for the reception f the head. The plates beingretracted,the pail may be readily Withdrawn from the mold or cone.

' I am aWa-rethatan inner perforated conical former made in verticalsections, each of which is provided with a narrow transverse rib, andcapable of 'being expanded and contracted Within an outer perforatedformer, so as to produce a paper-pulp pail with a croze, has heretoforebeen employed; that an inner conical former has heretofore been employedwith a detachable flaring former of less diameter placed thereon to forma shoulder at their junction,'near the small end of the pail, to supportits bottom; that shoulders haveheretoforebeen formed onpaper-pulpbarrels and pails to su pport'the heads of the former and the bottom ofthe latter; and that a projectible and retractible ange movingindependently of a former has heretofore been used for forming a 7ocroze in a pail, and therefore l lay no claim to either of theseconstructions, my invention being limitedV to the construction andcombination of parts, as hereinafter claimed.

What I claim as my invention is The combination, with the former G andspiderf, provided with the'recess a, of the ring A, having the eccentricslots h, slotted segmental plates B, pins d, and screwsc g,substantially as described, and for the purpose 8o set forth.

EBER HUBBARD.
